--- Comment #9 from Anastasius Focht focht@gmx.net --- Hello Louis,
--- quote --- Is there a recipe ATM to get .NET Framework 4.x properly installed in 64-bit WINEPREFIX? --- quote ---
no, not in a clean way.
It's essentially manual extraction of some dlls from {.msi,.msu,.mzz} packages and putting them in proper 64-bit locations. The underlying 32-bit/64-bit MSI client/server insufficiencies and mixed 32-bit/64-bit MSI package handling bugs causing this are already documented. I don't want to have these bugs ignored/stalled for more years just because workarounds exist with winetricks. We already had this in the past with various other issues. No one will bother/attempt to fix them if there is no pressure from end users.
If you provide winetricks hacked recipe(s) for working mixed mode 32-bit/64-bit .NET Framework installation in 64-bit WINEPREFIX, then go on. You should be prepared to provide support for bug reports resulting from these on your own.
Regards
